Note 1: Of all the Summary weapon codes, three are not available in NIBRS—55-Pushed or thrown, 75-Drowning, and 80-Strangulation.

Note 2: Although NIBRS allows for up to three types of weapons to be reported with an incident, the Supplementary Homicide Report allows for only one to be associated with a murder offense. However, the issue of which weapon to report with the offense is automatically handled by choosing the weapon from the incident that appears first in the list above, thereby applying a weapon hierarchy. For example, if a murder involves both personal weapons and explosives, convert the weapon as personal weapons because that weapon comes before explosives in the listing above.

Circumstances

To determine the Summary Murder circumstance code from a NIBRS Murder Incident Report, perform the following steps until a circumstance is determined:

1.

Check for an accompanying Part I offense. (See below, Summary code—Part I offenses. For classifying purposes, Summary codes are listed in order of importance.)

2.

Check for an accompanying Part II offense or NIBRS Aggravated Assault/Homicide circumstance code. (See below, Summary code—Part II offenses. For classifying purposes, Summary codes are listed in order of importance.)

3.

Continue through the list of nonfelony-type circumstances until the Summary Murder circumstance is determined from the NIBRS information submitted for the incident. (See below, Other than felony-type murders. For classifying purposes, Summary codes are listed in order of importance.)
